Comparative Study
Stereoscopic versus monoscopic viewing of aneurysms: experience of a single institution with a novel stereoscopic viewing system.
Stereoscopic viewing of computed tomographic angiography (CT-A) or magnetic resonance angiograms might increase the diagnostic potential of these imaging techniques. Our aim was to evaluate the benefits of a novel stereoscopic viewing system for aneurysm detection compared with standard monoscopic viewing. ⋯ Stereoscopic viewing of CT-As increases the diagnostic accuracy and represents a promising technique to reduce the need for invasive DSA.

Multicenter Study Observational Study
Intelligent Surgeon's Arm Supporting System iArmS in Microscopic Neurosurgery Utilizing Robotic Technology.
Based on our previous reports, stabilizing the surgeon's arm with an intraoperative armrest is linked to improved precision of microsurgical and endoscopic procedures. We developed the robotic intelligent surgeon's arm supporting system iArmS, which automatically follows the surgeon's arm and fixes it at an adequate position. ⋯ iArmS allows continuous precise manipulations that provide high-quality surgical results in neurosurgical techniques. Moreover, iArmS is a useful automatic tool for holding and following the surgeon's arm.

Review Case Reports
Traumatic Unilateral L3-4 Jumped Facet Treated with Open Reduction and Short Segment Fusion.
Facet dislocations, or jumped facets, are part of a spectrum of flexion-distraction spine injuries. Bilateral and unilateral facet dislocations are commonly seen in the cervical spine. Traumatic jumped facets in the lumbar spine are rare injuries, and most involve the lumbosacral junction. Lumbar facet subluxations occur commonly in young patients owing to flexion-distraction forces on the lumbar spine at the time of injury combined with ligamentous laxity that exists in young patients. ⋯ Following anatomic reduction, unilateral jumped facets can be effectively treated with instrumented stabilization. This report provides evidence for the durability of short segment arthrodesis in select cases of a rare lumbar facet subluxation.

Review Case Reports
Intradural Juvenile Xanthogranuloma with Involvement of Multiple Nerve Roots: A Case Report and Review of the Literature.
Juvenile xanthogranuloma (JXG) is a rare, non-Langerhans cell histiocytic disorder that primarily presents as multiple cutaneous lesions in young males. Solitary lesions in the spinal column are an especially rare presentation of this disease, and central nervous system involvement can portend a poor prognosis. We report an unusual case of an adult woman with an unresectable JXG of the lumbar spine. A review of the reported cases of thoracolumbar JXG and the current data regarding diagnosis and treatment are presented. ⋯ JXG of the spine is a rare disease with nonspecific clinical and radiographic findings that can make it difficult to diagnose and dictates the use of immunohistochemical staining. If possible, total surgical resection will offer the best outcomes; however, other modalities such as chemotherapy can be viable alternatives or adjuvant modalities.

Review Case Reports
Intracranial Giant Mycotic Aneurysm without Endocarditis and Vasculitis: Report of Rare Entity and Review of Literature.
Infectious aneurysm is a rare complication in intracranial aneurysm. Moreover, giant aneurysm is a rare entity in intracranial aneurysm. In the great majority of infectious intracranial aneurysms, vasculitis and/or endocarditis is associated. ⋯ This bacterium seems to be more and more frequent in North America and Europe, according to the current literature. Moreover, cases of mycotic extracranial aneurysm were reported. Here we report the first case of intracranial giant infectious aneurysm in an adult patient, without any endocarditis or vasculitis. This new entity could be the cause of a bacterial graft on an asymptomatic giant preexisting intracranial aneurysm or a consequence of campylobacteriosis.
